Analysis of comprehensive operation efficiency of urban environmental sanitation in China

Abstract ABASTRACT With the development of China’s economy, the level of Urban Environmental Sanitation management has far-reaching impact on the ecological environment. The well comprehensive operation efficiency of urban environmental sanitation in China can help China achieve the goal of carbon peak and carbon neutralization. The study applied data envelopment analysis (DEA) and Malmquist productivity index (MPI) to explore the comprehensive operation efficiency of urban environmental sanitation in China. The statistical data of the 31 provinces over the period of 2017 to 2021 are gathered as inputs and outputs of the DEA model and MPI model. It finds out that the mean of comprehensive operation efficiency of urban environmental sanitation in each year during the research period was no DEA efficiency in general. The change trend of MPI from 2017 to 2021 was negative growth. According to MPI and its decomposition of China by nation, Technology Change (Techch) was the main driving factor of MPI growth. Comprehensive operation efficiency of urban environmental sanitation should be expanded and the technology innovation of Urban facilities in China needs to be promoted vigorously.
